C# - Convert String To Specific DateTime Format?
Jul 30, 2010
I've been googling for a while now and for the life of me can't seem to find a solution. I thought this would be easy but it's taking too long and am turning to stackoverflow.
I need to convert a string which contains a date and time to a DateTime variable. I've formatted the string in the exact format I want to store it in but when i convert it to a DateTime it keeps adding the seconds which I don't want. I want it stored as 01/01/2010 09:00AM. Here's the code I've been using so far:
DateTime.ParseExact(startTime,"MM/dd/yyyy hh:mmtt", null);

I have the following date in string format "2011-29-01 12:00 am" . Now I am trying to convert that to datetime format with the following code:
DateTime.TryParse(dateTime, out dt);
But I am alwayws getting dt as {1/1/0001 12:00:00 AM} , Can you tell me why ? and how can I convert that string to date.
EDIT:
I just saw everybody mentioned to use format argument. I will mention now that I can't use the format parameter as I have some setting to select the custom dateformat what user wants, and based on that user is able to get the date in textbox in that format automatically via jQuery datepicker.

I have an application that uses a time date picker control to display a date from a sql (sql 2000) table. Casting from the table to the control works fine, but writing a selected date from the control back to the database does not, I was under the impression that a datatype 'date' in VB would be compatible with SQL datetime datatime, and obviously it is from sql to vb as the date is correctly displayed in the control reading from the table. How do I need to convert the value from the date time picker control to write into sql ?

I keep getting errors when I try to convert. I have a date row that when my page loads it displays as
1/28/2010 12:00:00 AM.
I have my default value set to '00:00:00" for it. I'm trying to convert it to 24 hour format so that it will read out as 00:00:00 initially. SQL Statement(The one that is working)
SELECT user_id, bpi_title, HoR, Date, Duration FROM tblViewLog2
JOIN tblBPIModules on tblViewLog2.module_id = tblBPIModules.id
I assume that I need to modify my SQL statement, but I'm having a hard time with the exact syntax. I'm trying to figure out exactly what I need to do with the information below in order to get what I want.
14 or 114
24 hour time with milliseconds.
HH:mm:ss:fff
21:00:00:000

I have a table in my SQL DB that is a DateTime table, what I want to do is take the numeric datetime it stores and convert it to a long date (i.e. 12/12/2012 conversts to December 12, 2012). Seaching the forums it looks like the string.format is the way to go and searching for info on that I found [URL] which lists all the different formats but they do not list a formating string to convert to the format I want to use. Does anyone know what format string I would use to convert a numeric date to a long date like I want? And can you show it in a code example because I am not 100% sure I understand the code examples shown on that site.

I have project in development where string operations like "Hi " + variable + ", welcome to Project" are used at many places (given example is very minor one).
One of the requirement is to convert it to string.format style.
It is very long and tedious job, where I would not like to break earlier working code due to any human error might happen while converting it.
I would like to if any Macro or VS command which I can create to handle it. Just like we mark block of code and do Extract function in Re-factor options.

i know that we can do this e.g.
dim str as String = textbox1.text ' when date is in this format dd/MM/yyyy
dim date_time as Datetime = Date.ParseExact( str , "dd/MM/yyyy" , nothing)
it works fine but when the user but the date like this 9/9/2010 it gives error because the format is set "dd/MM/yyyy" and given date format is "d/M/yyyy" or it could be "dd/M/yyyy" what could be the solution of this problem?

In a simple ASPX page, I have an SqlDataSource and a DataList control bound to it.It shows 3 columns; UserName, DateTimeStamp, and Comment.The database table has these defined as nvarchar(24), datetime, and nvarchar(80).The UserName and DateTimeStamp are shown in the ItemTemplate as Labels, while the Comment is a multiline TextBox.I have an event handler for the OnTextChanged for the Comment so that I can update the table as soon as the user tabs off the TextBox.I use the UserName and DateTimeStamp as the Primary Key, and pass all 3 to a stored procedure, where the parameters are declared the same types as the table.What I'm getting though is an "Input string was not in the correct format", which can only be the DateTime that I am passing.
I've tried different date/time formats, but so far come up empty as to the one that will actually work from the C# code.All the different formats I've tried work fine if I pass them to the SP directly via Management Studio, but all throw an error when I use
SqlDataSource.UpdateParameters.Add("DateTimeStamp", System.Data.DbType.DateTime, lblDateTimeStamp.Text);

I inherited some project which uses crystal reports. The datasource for startdate is in string format but I would like to make it up so that the time does not get added. Should I change the sql query somehow or can I make from the object in crystal reports (IFieldObject) to something more manageable.

I have written a code to insert emp details into database and i am also inserting local date(i,e system date) into to the table to know/have an idea at what date the employee inserted details. I have set date format add/MM/yyyy and its working well in my local system, but after uploading the site into server (the server is shared server) iam getting error and the error message is Failed to convert parameter value from a String to a DateTime.
Surprisingly, it is working well in server when i chaged the date format to MM/dd/yyyy, but now its not working in my local system and getting the same error.

Datecol is a datetime in a sql table.
q="select convert(char(8),datecol1,112) from tblone where datecol2 is null"
is what I use for my query string for sqlcommand(). I'm getting the error "a field or property datecol1 could not be found in the datasource". Without the convert, the query is ok.

Currently I am able to bring the datetime from my SQL table but I also need the milisecods. Here is the line of code:
[Code]....
So latestTimeStamp = {9/22/2010 6:24:09 PM} but I needed it to be latestTimeStamp = {9/22/2010 6:24:09:080 PM}
since the SQL field value is 2010-09-22 18:24:09.080 and I want to do an accurate datetime comparison.

Just looking for some strategies to modify the typical
mm/dd/yy 00:00:00 to simply
mm/dd/yy of a datetime item being returned in a dataset that is bound to the gridview
the item is within a dataset and I am simply doing the following
gridview.DataSource = GetDataSet();
gridview.DataBind();
So I don't have a ton of interaction with the dataset at the moment. I could brute force iterate through it and do something like
foreach(Table)
foreach(Row)
grab date Col, format and concat to look as desired
but this is very messy and was wondering if there is a more elegant solution.
